I would respectfully suggest that the only reason to wait for an RP mk2 is that the original RP is 2+ years old and while stil great value for money, a replacement or similarly-priced R body may come as soon as late 2021 or early 2022. I do not miss IBIS as all the RF lenses I own are equipped with the latest IS. The non-L 24-240mm and 35mm 1.8 are great glass for their purpose, and the rather more costly 24-105L and 100-500L are superlative. A mirrorless body does not have the shake induced by the mirror, so even without IBIS you are ahead of a DSLR. The relatively light weight of the RP is achieved because (among other things) it has a lighter battery (LP 17) which may not be able to cope with the power drain of IBIS.
