Personally I don't see the graphical thing as something that's the biggest reason not to include siege weapons. Balance is the biggest one for me. I know how slow is the reaction of the developers for balance problems. Well, it wasn't intended as an insult, I am just stating a fact: after people see something is over/underpowered, usually a year passes before there is a new version which fixes these problems. Even with testing RCs it's like, each month we can have some changes in the balance, and the feedback itself takes time too. In my opinion, before we even will try to introduce siege weapons, we need to first estabilish a proper way of trying new things in balance. Temporary lobby settings for unit balance (only for an RC) or something like that could speed the balancing up - testers could change the unit stats themselves and try to look for better solutions. I know it's a very radical idea, but that's the only one I got so far.
As for singleplayer only, it feels strange for me to have two versions of the game (sorry TDL!

). I'd much rather take the similar-yet-more-consistent-with-the-rest-of-the-game approach: no siege workshop yet, only spawnable siege units. I dunno if I want to make them usable with dynamic scripts, since that might make people make their own siege workshops etc. Also, I propose to massively underpower them first, and then to start balancing the weapons "upwards" (let's try to make them kinda as useful as xbows are nowadays - not rly but sometimes why not). I really really am afraid to break the current unit balance.
One single thing that makes me stay distant from the whole siege and townhall affair is how persistently everybody here keeps complaining and raging at the devs. Really, for such an awesome game which improved over the years SO MUCH, there is no need to get almost emotional. Don't you already like what you see in the game? I am indifferent towards those TPR potential additions, but balance is everything for me and you don't really seem to appreciate that there'd be quite a bit of work needed, and also quite quite many things to be potentially screwed up.
That being said, I agree with dicso that in our current TS multiplayer gameplay, siege would be next to useless. I dunno about the townhall though, it largely depends if its role is changed to work better during peacetime etc.
