Candle, I'm not sure if it's because of how much of a visual-centric person I am, or your tendency to write run-on sentences, but I cannot make heads or tails of what you just said.
Are you listing changes yuo would make to the Canon excelsior to make it TOS like? Are you listing changes to the JJ-Abrams-style excelsior posted in this thread, or are you listing changes to the TOS excelsior made by atolm?
"The cargo doors id reshape to not be so flat more bubble type and taller as a result."
I don't understand. to what cargo doors are you referring? the cut outs on the back/bottom of the excelsior hull, or the shuttlebay on the top, stern-most end of the excelsior?
"impulse engines leave the line work, but remove the little balls on them flatten it out and add a line going down each strip to the engine exhast and instead of being curved make it more flat back but rounded tips like a connies with a an exhuase grid."
1) take a breath.
2) Again, I'm not really sure to which version of the presented designs you are referring to. What 'little balls'? are you referring to the impulse deflection crystal, or the little running lights? Further, to what curve in the impulse engine are you referring - once again, without knowing which excelsior you are referring to, its hard to guess what you are talking about.
Are you talking about this curve?
or one of these curves?
It may help to use more descriptive terms than "little ball" or "that curve there". Yes, using trek or even real-life ship architectural terminology seems a little pedantic, but using them makes it easier for people to follow along with what you are saying.
