Hi and welcome.
I'd say not possible to get a 01 without throwing an incredible amount of cash at EdGI parts I'm afraid.
The 02 fixes some of the issues the 01 has (90° sears and piston, less crappy locking pin, better cylinder to barrel volume ratio).
It still needs some TLC to turn it into a good gun (stock cylinder is still crap, hop rubber is nothing special and will break after very little use, AA hop wheel is mandatory for good consistent pressure).
But one thing you could do, if you have access to a 3d printer, is to buy the 02 and do the usual upgrades, but instead of dishing out for its dedicated suppressor you could simply buy a 01 outer barrel (i'm sure there is plenty to choose from, as most 01 users shortened down their guns to fix the air volume) and design, print/mill a barrel spacer + baffle chamber.
This will allow you to run the longer 550mm outer barrel with a 300mm inner, and use the remaining outer barrel lenght as an integrated suppressor.
Win-Win really. You get the look you want and still have a perfectly functional gun
