I'd be very supportive of the single Troops "Boyz" entry, with some qualifications like:
Heavy Weapons are per X Boyz (ie 1 heavy per 5 or 8 or 10 Boyz) to avoid Min-maxing.
Skills: like Tank Hunter - lifting the Heavy Weapons limits, but with restrictions on Mob size.
Nob/Mek upgrades linked to weapon selection.
Frag/Krak Stikbommas - heck the models would likely sell better if they were a viable Troops choice.
Improving the Lootas, for their cost they just aren't worth it.
Definately linking Mob check (et al) to wounds vs size.
Some version of Str4, whether on the charge or not, fix the Choppa or something.
Personally Str4 Orks with Choppa giving -1 to Armour Saves would be perfect.
Dropping 0-1 on all units.
Warboss Stats linked to cost (like 3rd Ed Marine Commander). IE Nob level, Warboss level (current), WAAARGHBOSS level (start about 200pts Str6 T6 ).
