Would this work?

Four 2' compact T5 6400k bulbs (20,000 lumens) for vegging 10 plants. And then a bunch of 300 watt soft light CFL bulbs for flowering? I think it would. Ik the veg part would. I'm more concerned about the flowering.

You want to have a minimum of 100 wats per plant i believe. Maybe you could just keep the fluoros on it and add the 300 watt cfl when you switch to flower. Have different light spectrums on it.

10 plants wit take FOREVER to bud under 300cfl watts. even if u have em one inch away

it would work but..an indica that the breeder says flowers in 8-9 weeks would take 15-20 weeks to flower... id veg and flower under the t-5s and clfs if i had that set-up
