I have just gone through a similar transition but for different reasons. Have had a GT1.9JTDM from new in 2006 and have absolutely loved it - compact size, styling, performance, handling, practicality given its a coupe - its been just brilliant and I've been very lucky having practically no problems in 80,000 miles. But its time to change so considered another GT but have been put off because its at the end of its life & hasn't really been developed further than the one I already have plus to get the colour/trim & specs I would want costs around £26K so poor value. Considered a Cloverleaf but don't like black interiors and not fussed about the wheels either so unfortunately it seems a new GT is out. Looked at a Brera but the lack of rear room knocked that out too. Eventually dealer convinced me to go for a new 159Ti instead on the basis of it being a more up to date platform and I have ordered a 2.0JTDM. Although I have only test driven the Ti impressions are that its altogether bigger & heavier car than the GT and that takes the edge off the performance compared to the GT so not expecting it to be as much fun overall. When I first drove a GT it immediately felt right for me and that impression hasn't changed over the 4 years I've had it. Impressions after driving the Ti were that it was a bit of a letdown and its not going to be the same fun although its got great looks, better ride, quieter and much more room of course. However, I spend a lot of time driving on my own so can press on a bit particularly on windy roads but think the Ti will turn me into more of a cruiser - time will tell. If I was in your position I would stick with the GT and start to enjoy it.
