supra wing tips with no spars

I have made 2 wing tips for my Supra wing about 2 yrs ago.

Unfortunately I did not fit a spar.
The wings are ply root ribs, wire joiners, unicarbon lay up at the root and 25gsm over the rest.

Will they be strong enough for a hand tow (not f3J winch launch).

If not any ideas how to rero fit some spars.
