MKI's airframe is not as strong as the airframe for MK2 and su-34.
Empty 32,020 lb (17,700 kg)
Typical Load (Su-30M) 52,910 lb (24,000 kg)
(Su-30MKI) 56,590 lb (25,670 kg)
Max Takeoff (Su-30M) 73,855 lb (33,500 kg)
(Su-30MKI) 74,955 lb (34,000 kg)
Fuel Capacity 20,725 lb (9,400 kg)
33.5 - 9.4 - 17.7 = 24.1 - 17.7 = 6.4
using maximum fuel, you get 6400 KG for payload.
also, I don't think MKI's can handle as much payload as su-34, because its airframe is not as strong as su-34 or mkk2 for that matter.
Also, you have to remember that 9400 KG of fuel on a flanker doesn't go as far as 8000 kG of fuel on a typhoon, since typhoon is probably 60% of a flanker's weight. So, if typhoon does load 3 external tank, I would think it's operation range would not be any less than that of a flanker.
As for typhoon vs Rafale, I think it's generally been mentionned that typhoon's turn rates figures are very good. It supposedly even exceeded F-22's rates at high speeds. I'd imagine it would be more manuverable than Rafale. Especially since typhoon was developed with more air superiority in mind than Rafale. Also, the range on typhoon's radar scans much farther, although it is easier to be jammed than RBE2. typhoon > Rafale in A2A, Rafale >> typhoon in A2G
As for Mig-29 to Mig-35, you can upgrade old Mig-29s to SMT standards, by it would not be upgradable to Mig-35, because you most likely need airframe change to handle the TVC nozzle.
