...I want to do the underpainting in oils, and then when that's dry go over it in acrylics. Can I?

I should add that the oil underpainting will be ultramarine and burnt umber in a 1part oil, 3 parts thinner, and 1/2 varnish medium, which I will paint over the surface and subtract out the lights. I'd do it in acrylics, but they would dry too fast for what I want to do. And I don't want to do the rest of it in oil because it would take too long.

Don't do it - although the oil underpainting may feel dry, it will still take months to cure, even if you've thinned it down. Oils cure by oxidation, so the oxygen must reach the paint. If you cover it with acrylic, it won't cure properly and the acrylic will discolour at best, peel off at worst, and the results may not be seen for years to come.
If you want to paint fast in oils, use an Alkyd medium such as Liquin or Galkyd to speed the drying - as fast as 6 hours in a warm dry atmosphere.
I'm not a great advocate of acrylic underpaintings for oils either - the oils need a semi-porous surface on which to adhere, and acrylics just don't provide that.

that's purely a rely of non-public determination. you're able to do something in acrylics which you're able to do with watercolors, and fairly some the failings you're able to do with oil portray. the single actual benefit to grease portray is which you additionally could make thinner and thinner colorations of a coloration to characteristic a semi-sparkling consequence to a painted merchandise. In acrylics this might't be carried out, as a thinner acrylic won't adhere to a thicker acrylic below it. cleansing up with maximum oil paints demands very poisonous chemical components. even with the undeniable fact that there are actually soy based oil paints that would properly be wiped sparkling up with cleansing soap and water. have relaxing portray!

No you can't. You can paint oil over acrylic, but not acrylic over oil. It might look like it works at first, but oil paint is oil based and acrylic is water based. The oil paint will cause the acrylic to peel off, flake, crack, etc.
You could do an underpainting in acrylics and then go over it in oils.

Best to use all the same type of paint - they make dry time extenders for acrylics that may give you the time you need. Otherwise, you have to underpaint with acrylic and use the oils on top.

Acrylic peels away from oil paint

Hmm...I don't think it will work like that. I've heard of oil on oil, but never on acryl on oils. Try and see if it works, I don't think it will take that long to see the result.

After your oil under painting is dry then cover with a clear gesso and then use acrylic paints. I've seen Bob Ross do it on some of his paintings.

Acrylics will paint on almost any surface. You shouldn't have any trouble painting on an oil painting as long as it is completely dry.

The "books" say don't but I have and 30 years later, no problem. But, I have only one or two cases so beware.
