Basically, the idea for your chassis is sound. However, there are a few
improvements possible.
You say you don't want to lower the ground clearance. That's possible, but
the suspension as you have it now is not without issues. In order to
compress, the wheel will have to move outward a little and depending on
the surface your vehicle will be driving on this can be a problem. The
best way to build suspensions is with the carrying arms as much horizontal
as possible. Try the concept you designed using the bricks that you have;
you will see it works better the more horizontal the arms get.
Also, you will probably find that you wear out or break the universal
joints in the drive axles. They are used under a rather extreme angle in
your design and subjected to a lot of stress. Why not connect the wheels
directly to the motors (since you don't gear up or down anyway)?
