There should be no major reason that adapting SnapLock and spiral to work together will be an issue, but please be aware of air flow direction. SnapLock has crimped ends and they need to be facing the correct way so that material doesn't get stuck in the protrusions. SnapLock isn't going to be quite as smooth inside for the same reason. HVAC wyes, for example are "backwards" for DC use because the air flow is the exact opposite direction from the normal use of these fittings. I recommend you try and obtain DC oriented wyes for that reason, despite the fact that they do cost a bit more.
