Yugoland should be possible, with FT17 and R35s on the lowest tiers, fill in with partisan captures (Hotchkiss, Somua, italian models etc) and before you know it you have reached T-34.....
Tier 1 - LT - FT-17 or NC M.28
Tier 2 - LT - P-IIa-j, 37mm gun
Tier 3 - LT - Sh-IIa-j, 1938 specifications (35mm front armor, 35km/h, 47mm gun)
Tier 4 - LT - Sh-IIa-j, 1940 specifications (50mm front armor, 42km/h, 47mm gun, possibility of upgunning to a 76.5mm L/30 gun, pretty close how Hungarian Turan turned out)
Tier 5 - MT - there is nothing other than a proposal for a modernized Pz-IV with US 76mm M1 or M4A3E4 Sherman (with some parts of modernization proposals - V-34 engine, uparmor etc)
Tier 6 - MT - Vozilo-A (T-34-85 modernization) 50/45/45 hull and 100/82/60 turret armor) - 85mm M51 gun (souped up 85mm)
Tier 7 - MT - M-328/M-628 (further development of Tier 6), turret was based on M47 turret (60/45/45 and 105/52/50 turret armor) - 90mm M3 gun
Tier 8 - MT - M-320 - Basically a baby Leopard 1 (75/40/20 hull, 105/52/50 turret) - 90mm M36 gun
Tier 9 - MT - M-636 (90/60/45 hull, 160/90/50 turret) - 100mm D-10T2S gun
Tier 10 - MT - M636D/105mm (90/60/45 hull, 180/120/50 turret), 680 or 760 HP engine,), 105mm F-1 gun
All meds have at least 8 deg of the gun depression, mobility is generally good, but armor is generally poor.
Arty line is fully possible, but highly unlikely.
Tier 2 - SO-75 R-35 (75mm leIG on the turretless R-35)
Tier 3 - SO-150(H) M-3 (15cm sIG33 on Stuart chassis)
Tier 4 - SO-105(H) M-18 - M18 with turret mostly cut off, limiting traverse to a 120 deg and with 105mm howitzer installed)
Tier 5 - SO-122(H) M-4 - 122mm M-30 howitzer on Sherman chassis
Tier 6 - SO-155(H) T-34 - 155mm M1 howitzer on T-34 chassis
Tier 7 - SO-130(T)/155(T) M-4 - 130mm M-46 or 155mm M1 gun on modified (widened and lengthened) M-4 chassis
Tier 8 - SO-152(T)/155(T) T-54 - 152mm ML-20 or 155mm M1 on T-54 chassis
Tier 9 - SO-130(T)/155(T)/203 (H) T-54 - 130 or 155mm gun or 203mm howitzer on T-54 chassis
Tier 10 - SO-203 (T) T-55 - 203mm gun on the modified T-55 chassis
Full TD line is possible if there is no arty line with exception of Tier 8 where I have no idea what could fill a hole.
Tier 2 - Sh-I-d/Sh-I-j
Tier 3 - SO-75 M-3 (Stuart with 7.5cm PaK)
Tier 4 - SO-75 Mark 3 (7.5cm PaK on Pz-III chassis)
Tier 5 - SO-76/SO-85 Mark III - regunned StuG with either US 76mm M1 or Soviet 85mm gun
Tier 6 - Vozilo-B - basically tier 6 MT chassis with a modified M36 turret - 90mm M3 gun
Tier 7 - SO-122 (T) M-4 - Sherman with 122mm A-19 gun (in the turret)
Tier 8 - no candidate
Tier 9 - SO-130 (T) M-4.
Tier 10 - SO-130 (T) T-54
There are also a few light tanks, but more suitable for premiums.
For the premiums there is:
M4 (85) - tier 6 MT - 85mm upgunning proposal for Sherman
M-634 - tier 6 MT - M4A3E4 with V-34 engine (if there is no Sherman in regular tier 5)
SO-76 M-18 Mod - Tier 6 - M18 with V-54 engine
SO-90 M-36 Mod - Tier 7? - M36 with V-54/V-55 engine
M-18/AMX - tier 7 LT - M18 hull with AMX-13-75 turret
There was also mid 1950s light tank proposal that was supposed to use modified M18 turret (closed top and a coax added) but there is no info about chassis. There is early 1960s light tank proposal with 90mm M3/M36 gun but I have no info at all about it. Than there is 1970s proposal for a light tank with 100mm gun, but again no info at all (light tanks were not seriously considered anymore).
