I have three Meteor projects on my one-of-these-days list:
Reaper: as per the real Reaper, but with NF.11 outer wings as well to give 8 x guns.
Ripper: tankbuster with Trent turboprops, tip tanks, and a big centreline gun like the top profile from Greg's original post.
Raptor: night-fighter with the inaccurate longest nose option from the Matchbox kit and big, early AAMs on the wingtips (a single-seater really was used for early Red Dean trials whilst the latter was still a Folland project).
The idea is to do all three in company demonstrator-style colours with civilian reg.codes (G-REAP etc...) then put them on a tarmac base with a barrier, big name & info placards, and some suits and punters as if it's a display at an airshow. The backstory is that the RAF buy the DH.110 Vixen instead of the Javelin, thus leaving Glosters to rather desperately toute "advanced" Meteors to anyone who's interested, shortly before they go bust.
