short answer: yes definitely.
If you check out my semi-coherent ramblings over at
www.combatspecops.com i'm working on a mish-mash of game styles that incorporates stats-type progression and weapon details similar to what you have mentioned.
I have implemented a complete character-creation rpg style 'dice roll' system and have been making good progress on weapon-stats as well.
gameplay is going to be a combination of rts meets rpg/shooter gameplay...if i like it gameplay-wise it's probably going to be incorporated, much to the detriment of my internal development timetable ;}
