I'm sure you can. If you don't have a convenient Harbor Freight, you can pay much more for this identical system on Amazon:

Although honestly, if we did it again, we'd probably just pick our parts from scratch. We replaced quite a few of the stock items: the rope was constantly cited as the weakest link, so we bought quarter inch rope from Lowes instead; we felt the hooks were flimsy, so we removed them and threaded a knock off Park Tools hook straight onto the pulley instead, and we also bought 2x6s to mount them on and used decking screws we already had instead of the included hardware. But the pulley with the system is self-locking , which I really like. Not sure if you can buy them like that from the hardware store?
Anyway, the hardest bit imo was watching him balance precariously on a ladder whole installing it. Made me nauseous, but I'm terribly afraid of heights.

Idea #3 might be a bit much without some help each time. #2 isn't bad, but not "off the garage floor" and still could be a bit much with a heavy bike. Idea #1 might be a bit fiddly but would do the trick.
We have a tiny apartment with 8ft ceilings. A ceiling mount hoist each for two bikes was the way to go. Bikes are up out of the way to claim valuable floor and some wall space below.
if you happen to have high ceilings, maybe a pulley system could work? like one of these https://www.amazon.com/2004-Cycle-Products-Bike-Hoist/dp/B003TFOPJA/ref=sr_1_1?dchild=1&qid=1596029550&refinements=p_n_feature_keywords_browse-bin%3A7800849011&s=hi&sr=1-1
Have you considered a bike lift?

Pretty popular for cramped garages.
Edit: noticing you said roof rack isn't an option. Maybe that means no lift, either. Cheers.
the pulleys we use is pretty similiar to those. works great. our ceiling slants up, so we have the bikes well above our heads. if you have a dropper post, i run some paracord around the frame and up through the seat post, that way the weight of the bike sits on the frame as opposed to the post. some dropper posts (command post and gravity dropper) wont need this.
I like these pulley systems, easy to lift and gets them out of the way. https://www.amazon.ca/RAD-Cycle-Products-Bike-Hoist/dp/B003TFOPJA/ref=sr_1_1?ie=UTF8&qid=1546012773&sr=8-1&keywords=bike+pulley+storage

Oh good! They make really nice assisted options with pulleys in case the bike is especially heavy
Amazon! Here the link bike thingy
I have a pulley system from the roof. No issues holding the bike up because those suckers are screwed in 2x6 beams. https://www.amazon.com/dp/B003TFOPJA/ref=cm_sw_r_cp_apa_glt_fabc_5B654QFYYF2FR1NXNPSJ?_encoding=UTF8&psc=1

This one's nice and easy and you just let the rope down. Hook the wheels. And than use the pull to lift them on up over head!
Nice and easy.
Update--purchased and installed this set for my RadRunner. Easy to install and has worked great so far!
Great work! But you should consider hanging your bikes differently. Hung by the rim will put all the bike's weight on one point of the rim and possible warp it. I got these and they work great.
Get yourself a bike hoist: http://www.amazon.com/RAD-Cycle-Products-Bike-Hoist/dp/B003TFOPJA/ref=sr_1_1?ie=UTF8&qid=1386543665
Makes hanging them easy and quick. They are pretty cheap right now ($20 for two).
