I like the ship and concept. I have a few different ships that I use for 'ground' support when I go into nearly any planet-side base situations.
For my .02 credits thoughts, I'd stick to Prismatics for shielding due to the fact they can last longer when hot lead and lasers start to fly in a combat zone. This has saved my butt on several occasions and may allow you to drop the fighter and use that spot for other modules (Guardian FSD Booster comes to mind to add to the 'jump' legs). You could also go with a level one size lower on the Prismatics than your regular shield and get the same protection.
If you stick with Prismatics, there are several ways to improve via engineer and experimental effects to last longer in the combat zone. I have to admit, it's my preferred shielding to go with...so I may have a little bit of a bias.
