I think your flooring idea would work!  As iamcuriositycat said, you have to try out different things and figure out what works best for you and what you like best.  Just know it can be done!  
		
		
	
	
I don't handle mine that often.  They aren't as tame as they could be if I worked with them a lot.  I sit in front of their cage and I they will walk right out past me.  I've swept with a broom right near one hen and she turned around and looked at it like, "Oh, where did you come from."  I though, luckily, these aren't wild birds, they wouldn't survive long.
I let them out almost every day and pick them up to put them back in their cage at night.  I talk to them a bit and check on them before they go back in.  Some are easier to handle than others.  It's all personality at that point.  I have one hen that is really docile.  She's always come right up to check me out.  Some of the hens are more stand-offish.  The roos are more proud!
They do imprint, but if you have them together, they imprint on each other rather than you.  I haven't spent enough time with mine to have them imprint on me.  
Part of the reason I don't handle them often is that we have handfed budgies and a lovebird in the same room and I try not to cross contaminate as much as possible.  So I don't handle the cage birds and the quail at the same time.  My cage birds come first and the quail are the 2nd class citizens.  The lovebird is always on me, so I don't want to touch the quail then have to grab the lovebird out of whatever mischief he's doing.
I would think that if you handled them a lot as chicks and consistently, they would tame really nice.  
As a teen, I had a hen that I received fully grown and I kept her alone.  She was very tame and would come when I called her.  She was never a pet (keep in a battery breeder cage) until I received her.  She was just one of those special birds.
