3.5 swap?

So I've had alot of time to mull this car over while gathering parts and pieces. And I've been thinking alot about the engine fitting into the engine compartment. The 3.5 just like the lx 5.7/6.1 is a front sump engine and unlike the 5.7 there really isn't any aftermarket support. I could modify the oil pan but it's aluminum and I'm not able to do that kind of welding.

I have a rack from a lx charger that I would really like to use in my dart so this way modifying my k member I can build some mounts for the steering gear.

Anyways I was just thinking about cutting the center out of a kmember I have around here and building a tube section to clear the oil pan of the 3.5(and maybe a 6.1 someday down the road :D)

so basically the stock k member:


and my idea:

So the blue is spindles, green is tie rods, red is the steering rack, and the black is the area that would be modified.
