Well you could do some Artillery, but I think you have a hole in your unit. It is good to hold a line, but can't herd/hunt.
I'd think about a hover lance that can also spot for those LRMs. Some options would be the fulcrum, saladin, scimitar, saracen
Fast hovers to get back shots, scout, and herd into your heavy forces, plus indirect LRM fire awesomeness (when your infantry can't do it)
