...and when they get at the roundabout the tape stops!!! Oh mááán :-(

No, seriously, all modifications are personalisations and as such per definition personal.
Also there is no getting around that the OEM compromise can NOT be improved upon. Any gain sómewhere is more loss in other aspects.
You know what you want and how to get there; accept that hotter cams and lighter flywheel will delete the pottering about mode. Kuddos to you whereas 99% of MX owners will think you ruined a perfectly good car.
Girls are a lot simpler as there is no set of homologation rules with periodic inspections. Despite what a lot of people perceive about the social conventions, there is no OEM optimal compromise within legal requirements; conscenting adults is enough, no drawbacks
Combining the two you can both have and eat your cake; whizz about in a manga car with a hentai girl. Preferrably under the sun; both for the whizzing and her dress code...
Hat off to you RobDad.
