Yes, you can oil paint over FULLY DRIED acrylic gel or paste.
Acrylic gesso is essentially the same thing, and oil painters have been painting over it for at least the last half century. The filler in the gesso gives it a "tooth" whereas the straight gel (paste) would lack that bonus.
Whenever doing a knife painting using ACRYLIC PAINT, I always blend my tube colors with acrylic gel. But for the same impasto effect with oils I use a stiff oil paint. If it's not stiff enough as it comes from the tube, I stiffen it with judicious additions of inert filler (marble dust).
