Painting - Nightmare (Latex over oil-based paint)

I accidently painted all the trim and doors in my house with a latex (semi-gloss) enamel. The nightmare is I found out when paint started peeling here and there is that all the trim and doors had been painted with an oil based semi-gloss.

My question is; Is there any other way to fix this besides stripping all the latex off because that would be a nightmare.

I was wondering if I could etch what I have on the trim now with a liquid paint etch, then paint everything with an oil based paint again to lock it all in?

The proper fix is to scrape off everything that can be scrapped, sand what's left, prime with a premium oil-based primer, then top coat with premium latex or oil

I'd suggest a nice waterborne enamel for trim

There's no liquid etch fix for this, sorry

I agree I need to lightly sand the peeling areas. The trick is to do it lightly because you can scrape all of it off if you try hard enough. The question is after I lightly sand the damaged areas do you think the oil based primer and a coat of latex enamel will lock in the remainder of the latex enamel that's coated over the original oil?

If you remove any/all loosely/poorly adhering latex, you'll be fine

Primers won't "lock in" a poorly adhering previous paint job
(though they may give that appearance for a while, the chance of another failure is astronomical)
If you can run a putty knife over it, and it comes off, it's got to go

...... and I wouldn't sand lightly!! Start with an agressive sanding with 80 grit and then 120-150 grit prior to priming.

The primer will stick to the paint it is applied to BUT if that paint isn't bonded to the paint underneath it - it will peel, sooner or later!
