Love Hiromi's stuff!
Now that you mentioned Hiromi Uehara, having an acid bass or leads like on Kung Fu World Champion would've probably fit great with the breakbeat stuff and been pretty cool on this!
Good job!
Probably you could make those with Vital.
Something like a saw wave with a filter with with high resonance and having the cutoff controlled with a fast envelope so it closes fast gives the "squeling" sound from the cranked resonance on the filter like she has on Return Of The Kung-Fu World Champion.
Might give a try on making those myself too! Will share the presets on the jam discord if I ever get around to making something close enough sounding😄.
