Anna, my friend Russell Carpenter might have some objection to you calling his pride and joy something that's "not taken seriously". He's repainted XS458 more than once, keeps it in running condition and it regularly blasts down the runway at Cranfield.
A quick google found this:

As for crash n smash, they'll want to cut any Lightning for transport based on previous efforts. Best off contacting 11 Sqn to see how they moved theirs... properly... from Leeming to Coningsby.
