I think those are great ideas! I will try them out myself...
I've actually been experimenting with ozonated water and OP. I think it's a good idea to swish and gargle with either H202 or ozonated water after OP because of the residual bacteria/viruses left in the mouth from the oil. I've noticed that I can still taste the oil afterwards, even brushing, and some of it gets swallowed (which I know you're not supposed to do!). So, I would go OP, gargle with OW/H202, then brush (might as well soak that brush in the OW as well!). Clean mouth! Yay!
