What a comprehensive answer, thank you 
My scenario will definitely require more than 2000:1 require somewhere between 1000:1 and 1500:1 length/width ratio. Does that mean it's a deal breaker or it's still feasible and I'll just have to sacrifice some quality/accuracy? Or maybe is it possible to do some tricks like connecting one shorter fragment to another (which is fine by me in my scenario)? I should have note it in my previous post: I'm targeting desktop.
Thank you for your time.
EDIT: I had my ratios wrong.
