It is REALLY awkward to work based off of a partial conversation...
I like to think that we could have our engineers look over it and correct all the Can horribleness while keeping an eye out for speed improvements. We are working from designs here, so putting a different engine onto the drive shaft is probably not a big deal, upscaling the shaft and prop a touch ought not to be the all that horrifically arduous and ought to have massive proportional increases in load bearing compared to the actual change, what with benefiting from the area of a circle... Knocking the front and back turrets down from three guns to two, again, ought not be that horrific and ought to have noticeable weight savings. So long as we have speed enough to render the Vickies irrelevant to hunting down our fleets it would be helpful. I mean, ultimately, we are drawing up new plans, fabricating new fabricators, converting from horrible metrics to wonderful Metric.... It is a big job, but it is also an easy occasion to make small changes. Now, if our good engines are still worse than their bad engines, then we don'tt have a better engine so we can't just slot out one and slot in another. If our engine is significantly larger or requires significantly more ventilation or something, then, again, it would be beyond the scope of "do this AND remove complex". But if there are simple ways to get dramatic improvements then it should be relatively easy to achieve both objectives... And it should be pretty apparent that something is simple or not when you see the dimensions either do or do not fit within the space available. I mean, sure, maybe there is a pipe somewhere that is difficult to plot into a three-dimensional space or something, but, ehh, I like to think that our engineers have competent moments.
