If you insist on using Citrix to run local versions of IE on your WAN you will eventually encounter bandwidth problems. Citrix will be competing with every other application on your WAN for bandwidth. To support the added user base would require you to expand your bandwidth internally. The performance is really unpredictable and can be bursty. User frustration will grow from an seemingly unresponsive server. This is not a position that you want key customers to be in. I've heard of stories where one print job brought Citrix to its knees because of its size and how bursty it is.
You argue that the TCO will be less by using the existing infrastructure. I think it would be more because you are including a very expensive application in the mix that is no longer necessary with the new requirements.
