Hi, I've registered on this forum some time ago but this is my first post because I wanted to give you some feedback on this.
You have currently done a splendid job recreating this mode, what you've done so far surpasses most, if not all, of the Unreal community efforts to bring back AS to UT3, congrats on that!
Although, you have still a long way to go, I don't know if you are working alone on this but if so, may I suggest you to form a team so it's easier for you to complete this? There are still lots of issues with this but I believe that with the appropriate support from the community fans will be playing AS on UT3 in a few months.
What I think you should do, also, is to spread the word and show everyone your work so far, so that the community may help you as much as possible, for example, show your assault mod in every website regarding Unreal and UE games, starting with EPIC forums.
Finally, put up some screenshots and deeper information on this in the first post so people feel attracted to try this!
