What is worth doing depends on the eventual Crossrail service. If, as is
likely, Crossrail is extended to Reading (and especially if it is also
extended to Reading via Heathrow) there aren't likely to be any Relief
Line trains from Paddington terminus. It would then be better to abolish
platforms 13 and 14, and extend 12 to full length (also allowing access to
12 with a full length train in 11). Is there any scope for making 12 an
island, after the style of Kings Cross platform 0?

AFAIAA they are going to convert P12/P13 into a full length platform, but I
haven't seen it in anything official yet. With P14 then ending up as the
only short platform. As you suggest, with most of the relief service
diverted to Crossrail, and the Greenfords removed, and electrification
allowing for EMUs (probably in multiple so 8 car) covering the remaining
semi-fast services, there is hardly any practical advantage to the OP's
proposal.
