If you think it is worth it, then go for it I thought it was worth it a long time ago, I managed to get my hands on several strains and chose the best of them my William's wonder and second best blue frost, I did F2 from blue frost but my WW I back crossed it several times and I got great seeds with high stability 87.5%, 1 more back crossing, and they would have been legit F1s but the results are awesome, every time I plant them, I get stable phenos, sprout flawlessly and are in freezer for 10yrs +...
Anyway you absolutely do NOT need to seed your entire grow the way that you want to do it, because you will lose your entire crop that way, all that you need to do is to get a box with cfls in and place some male closes 12/12 then gather pollen, then isolate one female, chose a bud or 2, using a paintbrush pollinate that bud or 2, then spray it with water after like an hour or less, that will kill excess pollen, and return your female to its flowering chamber. you can freeze pollen for a while as well, I used to place it in airtight containers with rice as dessicant, same way I do with seeds. It might sound complicated, to some it might be, but to me, it's just science, and art, I love doing such things. I have this greenhouse where I would take my morning coffee at dawn and a paintbrush and pollinate my cucumber plants, it is one of my favourite morning activities.
