Is the stucco smooth under the paint? Reason I ask, is some is very textured, and you couldn't apply enough glue to make anything stick. Basically a flat surface, with a lightly sanded finish is best to apply anything to. Make sure to scrap any loose paint completely of before you sand. Any loose paint could be an area that loosens over time and allows your work to be foiled.

Yes, it's smooth stucco. It's got a sandy texture, but otherwise smooth compared to "splatter style" stucco.

After removing the paint layer, I was planning on taking my angle grinder and do "long swoops" lightly to the stucco to roughen it up a bit.

It depends on what system was installed. generally there is a masonry outer layer applied on a concrete block or cast conc wall. If it is the sanded mortar over styrofoam aka EIFS then that is a different game. I would not apply heavy veneer over EIFS as it can crush the styrofoam. It is possible to attach support angle to inside structure but it pierces the seal and is inviting trouble.

My house was built in 1960 and doesn't have any styrofoam stuff.

I guess what I'm trying to figure out is if I need to apply a lathe later to the stucco itself or if it can just go straight onto the stucco after removing the paint and some slight roughness added.

If it were me I would get a wire cup and roughen up the wall to open the pores. But some of the expanded metal lathe and some metal roofing nails to fasten to the wall will work great (except for mashing fingers holding the nails). That is how me and Dad did rock veneer back in the day. I would guess that the roofing nails won't go in well so some hardened concrete nails will be in order. Believe it or not the masonry when spread on the wall will bond very well. We used the lathe on plywood and then rock w/ mortar and as far as I know it is still intact and that has been 20-30 years.
