The blockhead should still be free to buy, so just wear that with no other arms/legs (just the blockhead)

If you're wondering about the R15 Block package, it seems like Roblox has cut off all access to it here and while you could insert it into a Roblox Studio session, it may load incorrectly or not appear at all.
