I'm of a mind to leave mine as it came out of the factory.
That's what I do with mine, I buy exactly what car I want and tend to keep them for a good few years and it has nothing at all to do with resale, I just prefer to look at the build record and original order and keep it that way.
I also have an aversion to badges, spotlights and any form of stickers adorning cars but that's the minimalist in me, he says with a Plus 8

It's all about your personal preference, you have already made a BIG statement buying your Morgan

I agree about the interior, these trays just lie on top of the existing leather and simply lift out, they stay still by having shallow 'skirts'. I think a little differently about under the bonnet which might be a future target for me, I'm considering a better manifold and appropriate ECU.
I can understand you wanting a bit more power and why not, with 190 bhp and 235 ftlbs I'm happy enough not to upgrade lest I get in trouble with it.
Interestingly when I first fell in love with the plus 8 in 1970 the specification has varied very little with the advent of emissions regulations.
The good ladies Polo GTI is 192 bhp and identical torque to the Plus 8 so quite a coincidence, it's a Motorway muncher and B road fun all in one I love it when I can wrestle the wheel out of her grasp.
Your trays are excellent and as I said earlier if I needed more room I would copy your design, it's really neat.
My wife very seldom travels in the car so I have ample storage space
