At the end of the day you can work really hard and spend a lot of money to get less than you started with. The setup I'm picturing that you describe is likely to not have the anti dive in the E36 chassis that you want (It may remember I'm speculating based on little data.) and take a look at the ackerman of what youve done. Kudos for experimenting, new stuff comes from there...
As a benchmark, I've heard that the E46 chassis had > $90,000,000 in finite element analysis done to make the tub work in tandem with the suspension and tire package. (Of course they likely used the data for the whole car line... )
If I were going as far out as you are I'd cut the top off the strut towers and tube them with the camber and caster I wanted.
