No.................... (also do as RCP Phx said above while I was typing and making diagrams I now can't use...LOL)
While it will accomplish what you want, it will give you some weird steering & handling quirks at best. Be undriveable at worst.
1) There has to be a certain amount of separation vertically between the upper & lower mounts on the axle
2) There has to be a certain amount of vertical separation between the upper & lower mounts @ the frame
3) There has to be a certain ratio of the vertical separation of the axle & frame mounts and it is affected by many other factors
4) There has to be a certain amount of distance front to rear between the axle centerline & the mount centerline for both the upper & lower mounts @ the axle
5) There has to be a certain distance between the axle & frame mounts (think control arm length), and that length is related to the separation of the axle & frame side mounts AS WELL as the location of the axle & frame side mounts with respect to the vehicles center of gravity AND the axle centerline
These are all very interrelated, and can be changed and still work well, but it requires a lot of calculation and almost ALL parameters will have to change, not just the location of the 2 mounts to keep it safe. You can fudge a little here & there as RCP Phx said, but the amount you can safely 'fudge' is in % of total, not in inches.
If you change these, you can end up with an undriveable vehicle, as in acceleration can cause the axle to unload, or the suspension to compress, or braking can cause the same things.
Think of it this way.,...you have a lug wrench and you want to loosen a lug nut....what is easier......a 4 way with equal lengths (8") on both side of the center cross, or an 8" breaker bar so both hands are on the same side, or a 2' long breaker bar, but you can only put your hands right side by side up against the socket on the breaker bar.
Let's look at the axle side mounts you want to move...
Right now, stock, the lowers are below the axle centerline a few inches, and the uppers are above by a good amount. For example, lets say the lowers are 3" below and the uppers are 6" above. This does several things, but the main one is braking and acceleration both keep the axle in it's place since the mounts are on opposite sides of the centerline, which give counteractive forces to each (ie 1 in compression and 1 in tension at the same time).
Now, move the lowers up to the axle centerline like you want, and the uppers up to 9" above. You still have the 9" separation, but the axle centerline is now at the lower mount. This is not good in that a panic stop the force won't be applied between the mounts, but all @ 1 or even worse, all on 1 side of both of them.
Putting the mounts where you say you want to will let the front axle dive under acceleration, and lift under braking, which is almost the exact opposite of what you want.
Moving the mounts will almost double to force on the upper mount & arm, which are the weaker ones to begin with. Any rotational force in the stock config is split between the upper & lower mounts, but moving them like you want to do, any rotational force will be almost ALL on the upper mount.
Or try this......or just think about it..........
You have a triangular piece of wood (which simulates the upper, lower & body mount points as viewed from the side), and you want to push it with your finger so that it moves like a boat hull or rocket....1 point leading the way, and the other two following.
Is it easier to do that by pushing on the middle of 1 side, or by pushing on only 1 point ??
Now think of your finger as the force from the axle on the mount points (or triangle points). If you push on 1 point, the triangle spins and doesn't move forward. If you push on a side, the triangle moves basically in the direction you want instead of spinning. This is kinda what will happen to the axle if you put the mounts where you want to.
I hope you can understand what I am trying to say....basically there is a lot of work to get a 4 link to act right & SAFELY under all conditions, you can't just go moving them around. The drop bracket still maintain all of the relationships I mention at the beginning, but moving the axle side mounts won't.
I was gonna put up some diagrams, but there is no way to do so directly from my computer that I see.
