I want to do a drain and fill on the Honda during the next oil change. Apparently that only takes care of 1/3 of the fluid in the transmission. Is there any harm in sucking out 2-3 quarts out of the dipstick hole and replacing that a couple thousand miles before the drain and fill? Seems like a way more convenient way to get more new fluid in there...

I sucked about 4 quarts out previously with my car, added lubegard red and four fresh quarts of Valvoline maxlife atf and shift quality improved greatly. Worked for me!
Semis like you could just drain and fill,drive,and do it again just as easily.
That is a reasonable way to freshen up the ATF but not a very efficient way to do a total exchange of the ATF. You could have a drain installed in the transmission pan. The pan should come off once to replace the filter if it has one. Even if its only got a screen, that and any magnets should be wiped clean.
A Magnefine inline filter is a good addition.

I like to do it that way.

No harm at all.
I done that with Mityvac 7201 for my LS400 and E430. It's so convenience and fast without any mess.
The capacity of the LS400 is 8 quarts, I used 12 quarts and siphon/refill 4 times in 4 weeks, because I could only suck out 3 quarts at a time. Same procedure for the E430.

Yeah nothing wrong with it. Its like doing power steering fluid.
Though, its probably smarter to do something like that halfway between your fluid intervals, not just a few thousand before. If you pull out 2-3 quarts you've replaced, I dunno, %25 of the fluid, so %25 of the fluid when you drain it properly will pretty much be brand new fluid.

What do you think about this?
A lot of people do it this way. Many times its hard to pour in fresh ATF as fast as the transmission pump is pushing it out as the dipstick tube is not large enough. In that case, Pump out 3 QTs, stop engine, pour in 3 QTs. Repeat. I would also say that less than half the vehicles for normal drivers (cars, pickups, SUVs) have drain plugs.

The Hondas do have drain plugs. And no pan you can drop. Your only choices are drain & fill or extract and fill.
And Honda's recommendation for a "flush" is to drain and fill multiple times. So the answer to the OP's question is that it's a perfectly acceptable idea. I bet you're getting more than 25% out (but probably a bit less than 50%) either with the extractor or pulling the plug. But I'd suggest you do pull and drain once, not that you'll get much additional fluid, but just to wipe the metallic shavings off the magnetic drain plug bolt.
And I would only use Honda ATF-DW1 in there, but others have reported success with Valvoline Maxlife Multi-Import ATF and Amsoil ATF.
