I am working on a home brew rules set that I want to have the customization and multiclassing of 3.5 with the class powers and shared progression of 4.0.
How would you go about doing this?
strip out the powers (shared progression?) from the 4e classes and blend them into the 3.5 classes. Invent new base classes where needed.
3.5 doesn't have a "warlord"... so you might apply its powers to the bard.
G'luck... smacks of effort.
edit: or you could turn each 4e Class into a tremendous Feat-tree... again, smacks of effort. Might end up pretty damn cool though...
Magic Missile [wizard]
blahblahblah
Prerequisite: ??, must know Magic Missile (?)
Benefit: Magic Missile as an At Will spell-like ability.
advanced Cleave [fighter]
blahblahblah
Prerequisities: cleave feat
Benefit: whatever 4e's cleave does... I don't remember too clearly.
advanced great cleave [fighter]
.....
prerequisties: cleave, advanced cleave, great cleave
benefit: as 4e cleave, but every target you threaten.

I think you'd almost have to give everybody a feat per level (instead of 1, 3, 6, 9, etc) to make this work. If I had the 4e PHB, I might try this out myself.
