Although I don't recommend, I think it is doable.
People always struggle when transitioning onto a different aircraft, regardless of experience.
Most stories you hear when 10's of thousands hours airline pilots transitioning onto gliders or ultralights, struggling to land, fly, etc, however the more is true when single engine pilots transition onto twins or jets.
Twins are lots of aeroplanes, requiring you to be >ahead< of aircraft, at least 20-30sec, a skill which deteriorates with age regardless of experience. They also require specific knowledge about systems, emergencies, etc.. and again with age it takes probably double the time to learn.
If $ is not an issue, you could buy yourself a twin, find an instructor/school willing to teach, then keep flying your aircraft daily in all weather until it becomes muscle memory. Expect to solo after ~100+ hours, or whenever the instructor sign you off. Also check with insurance, they may not insure if you don't have certain number of hours.
Again, I don't recommend this path for reasons mentioned above, however with lots of $ and your persistence, anything is doable.
