It's really up to you on a personal level, it's probably do-able time-wise but you'll need to factor in complete end-to-end travel time for the journeys - flights may be favourable but if you live 2 hours from LHR, it may not work out that way.
Personally, my dad commuted to Stockholm when I was a kid in the late 90s for a fortnight at a time, and I think it worked out OK, but it was a short-term measure I think.
