Hi,
We have TXF and solvent Mimaki's and honestly after a lot of experience with the TXF I'm not sure I'd try to convert a solvent. The TXF has enough issues on it's own handling white ink and it's a purpose built machine for that. I'd imagine that a converted JV300 would be a hot mess. We converted our old JV300 to solvent and back to sublimation a few times and that wasn't that bad but DTF white ink is a PITA. I've got one paperweight TXF300 that's only a half year old with continuous white ink issues.
That being said, we demo'd printfactory and that'll easily handle your rip side for DTF and works well with Mimaki. It's a monthly subscription. We're sticking with Cadlink just because it's been insanely busy and we don't have time to switch but printfactory has some nice features.
At least on the West Coast this is the Printfactory guy:
