Should be easy then. (edit: for a partial. A bit hard for full extract, as 99% of the malt flavour is base grain.)....here you go.

AG BG 1034, volumes: 25.88 boil /20L batch, 32.9 IBU, 1045 OG
PM BG 1034, volumes: 13.46 boil /20L batch, 33.1 IBU 1046 OG
Should require 10L topup to achieve 20L. Have not accounted for any kettle losses, other than
evaporation and cooling.
IBU dependent on actual hop alpha. If need to adjust for hop alpha, leave the weights for the later
additions alone; only adjust the 60min weight until IBU matches.
Have subbed TF Golden promise for marris otter; if using MO, just use the same weight....personally, I
think the GP would give the better result. 2c.
heres the BSM (if you use beersmith, or for others that want it):
