I wouldn't do it if I were you. I cannot believe that the market is big enough to justify a shop; and whatever market there is, it'll definitely be shrinking very quickly at the moment.
It'll surely be cheaper to have an empty shop except for the problem of rates. If you can't get anyone to rent it out, let them have it for free as long as they pay the overheads.
Hold onto your cash while everyone else is losing theirs.
