You're on the right track.
NiMH is a perfectly viable alternative to LiPo pouches.
Look for a 7.2 nimh sub-c pack instead of AA cells however, such as this one.
Those sub-c cells will have a lot more current capabilities then an AA.
Replace the connector with an xt60/deans, and you'll get all the performance of a lipo, with no safety issues.
9.6v nimh packs are also a thing, and work acceptably for an 3S li-ion replacement, but a 6S NiMH pack much more closely aligns with 2S li-ion voltage than an 8S NiMH pack aligns with 3S li-ion voltage, so I'd start there. 9S NiMH packs in a good size are hard to find sadly.
Other alternatives is LiFePo4, which is available in 18650 cylindrical format/pouches, and high current 18650 cells in general.
But the simplest and easiest thing is to just grab a 7.2v sub-c NiMH pack and velcro it to the side of your blaster, then use any good motor designed for 7-8V, like M2s and 3240s. No safety issues, all the performance, downside is size and weight.
A single 7.2 v/2000 mAH NiMH battery pack will consistently light 3 Estes igniters, no problem. This is a 3000 mAH, but for illustration: https://www.amazon.ca/Tenergy-3000mAh-Battery-Tamiya-Connectors/dp/B0037U35SO/
Get the opposite Tamiya connector as well, connect it to the battery terminals on the Estes controller and done. I just use an elastic to hold the controller + battery together.

This can supply 30 amps. I probably need to search harder.
