Spare yourself the headache my friend. Some dreams are meant to stay dreams. Enjoy your jeep and don't look back.
One thing that the Land Rover community thought me, is a more mature approach to modifying a vehicle for offroading and overlanding. No overdoing anything and doing stuff moderately and intelligently is the Land Rover way to see things. Heck, they do the camel trophy and G4 expeditions on vitrually stock vehicles.
I am pleasently surprised that you seem to have that maturity already and would have been a great Rover owner. But as said, look ahead and not back. Unless you like to constantly fix stuff, enjoy using a jeep rather than fixing a Rover.
