Show design help

I’m trying to wrap my head around show length for my MIL’s upcoming 80th birthday. I’ve got 24x cakes (limited to 200g in Canada), 16 Roman candles, 4 barrages, 16 single shot florals, 2 fanned wipe slices, 7 fountains, and 5 flame pots. I’ll be using 2 ignite 18’s and I’d like to sync to music. -Is 80 ignitions realistic with 36 cues, using ignite talons? -what length of show should I be aiming for with what I have available? I was thinking 2 or 3 songs (10ish minutes) but can’t really figure out if that’s going to be enough or too long? Thanks for any input provided.
