Suggestion - reinforcing

I know there have been some suggestions about the reinforements thingy... And I'm about to make a new one (or at least I hope it is new).
I play now on Evony for the last 3 or 4 months, and there you can reinforce either your own cities or other people from your alliance (what a clan is here, but I hope you realised that already).
So, my first suggestion is: keep reinforcing limited to people in your own clan. It can be extended to allied clans if there would be an option to let the system know which clans you are allied with.
Probably a lot of you will not like this idea, but I can only try to propose it.
Second, on Evony you can't do anything yourself with troops one of your friends sent you, just like it is here. You can only send them back. However, if you send troops to one of your own cities, you can controll them as if they were trained in that village. So, my second suggestion is: maybe it can be implemented that you can also use troops from your main village or your outpost in your other village. If necessary it can be limited by the capacity of the barracks/stables/archeries: if the capacity is 100 and you have 60 units of that type in that village, you can send as much support as you want from another village, you'll only be able to controll 40 of them. Those units will 'find a new home there'.
What do you guys think?
Ps: it is only a suggestion, if you don't like it, so be it. Just don't tear the idea completely down please.
