Yes, why not, I am sure they will be pleased to see you.
You probably already understand fly a Moth is unlike a typical training aircraft. Inevitably they are harder to fly and require better technique.
If you have ever skied it is a bit like the difference between sking on a dry slope and the real stuff - the dry slope will be very revealing of poor technique.
A few have completed their PPL on a Tiger.
I would caution about changing mid stream if you had that in mind. Finish off your PPL first.
By all means take a pleasure flight in the Tiger - that will not do any harm - you might hate it, or you might love it! Come back and let us know.
