I haven't tried player models, but it's possible with other npcs like ambient ones, and ALL you need is openIV. Find the .meta file, like "ambientpedmodelsets.meta"

Scroll down to an easy-to-spawn-at location such as "STRIP_SC_MALE1 and STRIP_SC_MALE2" (the strip club near Franklin's aunt's house) where they all spawn inside or around the front door and find this:

<Item type="CAmbientModelSet">
<Name>STRIP_SC_MALE1</Name>
<Models>
<Item>
<Name>A_M_Y_SouCent_01</Name>
<Variations type="NULL" />
<Probability value="1.000000" />
</Item>****
<Item>
<Name>A_M_Y_SouCent_02</Name>
<Variations type="NULL" />
<Probability value="1.000000" />
</Item>
</Models>
</Item>
<Item type="CAmbientModelSet">"

And change it to something like this:

<Item type="CAmbientModelSet">
<Name>STRIP_SC_MALE1</Name>
<Models>
<Item>
<Name>A_C_CHIMP</Name>
<Variations type="CAmbientPedModelVariations">
<CompRestrictions />
<PropRestrictions />
<LoadOut />
</Variations>
<Probability value="25.000000" />
</Item>
<Item>
<Name>A_C_RHESUS</Name>
<Variations type="CAmbientPedModelVariations">
<CompRestrictions />
<PropRestrictions />
<LoadOut />
</Variations>
<Probability value="25.000000" />
</Item>
</Models>
</Item>
<Item type="CAmbientModelSet">

If you want to force a certain outfit or avoid one, you can try adding this:

<CompRestrictions>
<Item>
<Component>PV_COMP_UPPR</Component>
<DrawableIndex value="1" />
<Restriction>MustUse</Restriction>
</Item>
<Item>
<Component>PV_COMP_LOWR</Component>
<DrawableIndex value="0" />
<Restriction>MustUse</Restriction>
</Item>
<Item>
<Component>PV_COMP_ACCS</Component>
<DrawableIndex value="1" />
<Restriction>CantUse</Restriction>
</Item>
</CompRestrictions>

"0" is first option, 1 is 2nd, etc. So that would force upper skin/outfit no. 2, lowr skin/outfit no. 1, and avoid accessory no. 2.
If forced upper, lower, or accessory top/feet isn't appearing, there might be a conflict. I know the stripperlite model is weird like that as they have 2 different actual body fitments that do NOT cross-fit with each other, while the other stripper variants are w/o issue. Since the strip club saves you outside and everyone spawns inside, it's a very good spot to experiment to see what will at least work.
