Cheaper still, renew on a SIM. Cheaper than a single, less hassle, quieter, not governed by weather etc. That outfit at bournemouth are authorised to do it.
I can't believe lapsing it for a bit will make a difference with an airline. You have to renew it on their kit anyway unless they happen to operate Seminoles.
As the guy has already said your ATPLs are safe for 7 years after your last IR revalidation. Cheapest deal is to let it lapse for 5 years then renew.
Good luck.
