Upgrade to Pan European?

The question you really need to ask yourself are you able for the additional weight of a pan. They are 300 kg and this is a big increase over the xj900. I have a 300kg bike a k1200gt and the difference in the weight compared to my Deauville is very noticeable. When riding the weight difference is a bit more subtle but moving the k1200gt around the garage takes a lot more effort than the Deauville. If I drop a 300kg bike I will struggle to get it up, I did knock over the Deauville once and just managed to get it back up.

The Deuville and the xj900 are similar weight, the k1200 and the pan are similar weight so thats where my comparison comes from.

What will you be using the bike for and what's your budget?

The Pan is a capable bike but also a bit of a bus.

Unless you're planning on doing 5000km+ two-up tours in the near future, it's much more bike than you need.

Have you passed your test OP? Taken any additional training?

I agree that the real question is what will you be using it for.

I would think something like a Pan European would be great for just that — cruising effortlessly across a continent on motorways. Which would imho be intensely boring and better done on four wheels with a decent sound system and AC. (Actually, for the same reason, I don't get the GS fad… puts on riot helmet)

Generalising wildly, most motorcyclists avoid unnecessary journeys on motorways, and prefer twisties, both for riding pleasure and as a way of experiencing new places.

1100 had a death wobble issue, I think?

Only the police ones.

Yamaha FJR does a similar job to the Pan 1300 but it's a good bit lighter (I think).

I'd hang on to the XJ for a while, do your test, build up the skills a bit more, see what sort of riding you do and then maybe look at changing the bike.

Variety is the spice of life I suppose. Some motorcyclists change bikes all of the time. Funnily enough, I'm the complete opposite, I hang on to my stuff for ages…I've only ever sold 2!
