Oil primer over latex paint?

I've just bought a house that's about 85 years old, and I have just
sanded, pressure washed, and TSP-ed the exterior, in that order. I am
now ready to prime the house. The problem is, some of the cedar
siding has been replaced recently, and the entire exterior has been
painted with latex paint. I got *most* of it off by sanding, and
there's a lot of bare wood showing. I'd like to use an oil primer to
penetrate into that bare wood, but I'm worried about an oil primer
sticking to the existing latex paint.
I've searched the archives, but everything seems to deal with latex
over oil, not the other way around. I'm a bit worried, truthfully,
that I'm going to spend all this time (and money--everything's so damn
expensive these days) carefully applying a coat of primer to my new/
old house and it's going to be peeling off in 6 months.
Should I just sacrifice the penetration of the oil primer for the
compatibility of the latex?
TIA,

Nothing wrong with using oil primer over latex, and oil primer is choice
for cedar. If the latex
stuck through sanding and pw, it isn't going to come off. Might be good
to apply two coats
where you have bare wood. Be very serious about caulking.
Oil primer is for Bare wood. Not for going over Latex.
