A single 3s2200 will be more than enough to runon the standard Sullivan starter. Agreed not really a good idea to run in parallel as you get drain back from the higher to lower voltage one. Even at C30 you easily get 66 amps so not a lot of voltage drop. The preferred setup would be a 4S lipo but no problem with 3S
Keep it simple by staying away from too much complexity. If you can , replace the Sullivan wire with some heavier gauge battery wire and keep the length down to minimize voltage loss. Not sure of the original Sullivan lead gauge but was pretty small but they may have corrected that in more recent years.

Re: 3s2200 hooked up in parallel

Which starter ? I assume if you are talking smaller motors you most likely have the S600 - Hi Tork Starter - which is rated at 12v but under load it can suck as much as 80 amps. So a 3S 2200 pack will do fine but make sure it is at least a 40C+ rated pack.

with some basic assumptions in mind....

2200mah x 40c = Max AMP output of 88AMPS
If turning a smaller motor (40 size)I doubt you will suck 88amps.

I personally run 4s 2200 and it will turn a 35cc gasser ! However I do not fly the packs I use on my starters they used for this purpose only.

FYI
============
S651 - Megatron - 12-24v up to 100amps under max load
S600 - Hi Tork Starter - 12v up to 80 amps under max load
S601 Deluxe Hi-Tork Starter 12v up to 80 amps under max load
S598 - Hornet - 12v up to 25 amps under max load
