Actually "E" ... that is one of the reasons I went back to the basics.. there are a few things we need to do to bring 'er up to speed... but if it is at all possible I want to keep the same primary hull. The warp nacelles, sensor pod (with the added q-torp tubes ) , roll bar, Impulse engines, and an added "lower deck" to the primary hull if it is done correctly should bring it up to speed...with the following tech up grades:
1. Q-torps standard
2. Deflector dish and q-torps in the same pod with the sensors on the roll bar
3. expanded engineering section to accomodate for updated equipment
4. Up-graded impulse engines to accomodate for multivectoring technology to improve maneuverability
5. Up graded nacelles ... for obvious reasons to bring the Miranda up to late TNG specs.
If ya read the story line in GAW ... the USS Bass Master ( one of only a few X-CLC ships developed) ... was nearly distroyed in an effort to rescue and protect another Federation ship. AS a result of that .. It offered an opportunity to refit the ship and bring it into compliance with remaining ship designs that place the SeaWolf class Advanced Light Cruiser into the Federation line up with all of the appropriate upgrades.
