Can you take better pics? Close ups and in focus please.

It would help to see the dropouts, not the top bar. The axle can't protrude beyond the outside face of the dropout. Most shop-level bikes have thick enough dropouts, many dept store bikes do not.

I think the OP is referring to a seat post release adjustment. His current configuration/frame would need modified... if it can be done (I've never tried it).

No, I don't think the frame pictured would need to be modified. I have a QR seatpost binder on my junky commuter bike that is just the through-bolt, nut, and the QR lever...kind of like what you have pictured above but without the collar around the seat tube. It just clamps against the binder brazons instead of having a traditional binder nut/bolt in there.
I would caution however...frequently, when I'm riding that bike and wearing baggy shorts, the shorts leg will catch/snag on the QR handle. It has to be kept tight enough so that you don't accidently open the QR and experience a rapid descent in seat height (resulting in possible crash). Or, if it's tight enough to prevent that, depending on how hard you're peddling, then you run the risk of tearing your shorts.

If the bolt that is threaded into half of the brazed on piece is 5mm, then no thinnest QR are just that, 5mm ...
then you have to drill out , strip the threads , so a 5mm QR shaft can pass through..
Realize; your seat post and saddle will me more vulnerable to theft. thereafter.
Why do you feel you need this? a 4 or 5 mm hex wrench is light to keep in your pocket or tool bag..

Even if you could, why would you want to? You are in NYC, right? Quick release seatposts = stolen saddles and seatposts. Moreover, IMO, you get less seatpost slippage with a bolt rather than a QR. I have had both over the years.

Note: My seat and post wont be vulnerable to theft since I can remove and take them with me after I chain my bike in public.
Yes I live in NYC. A quick release ensures that my seat and post AREN'T stolen since I can just take them off my frame and take them with me while I my bike is chained up outside.
