I have 20 of the 5l easy kegs similar to the ones you get beer in from the supermarket.

Has anyone tried adding a Co2 valve to the top of these easy kegs 5lt?

Presta valves can be bought super cheap on eBay. Fill the kegs using a Co2 bike tyre inflator? Test the pressure in the kegs by hooking a cheap bike pump up to the valve after filling with the tyre Inflator?

Seems like a great way to be able to pour a pint, re pressurise using the Co2 tyre inflator then be able to keep that keg fresh for months after the first pint was poured?

I have like 20 of these mini kegs. Would appreciate if someone could let me know if this would work or not? I'm really not a huge beer drinker. If I want more than one or two drinks I'll always opt for the gin or wine. So it would be super helpful to be able to pour a pint or two then add Co2 to keep that same keg fresh for months before drawing another pint.

Have a look at these threads, lots of reports of these kegs leaving a metallic taint to the beer after a while.
5 or 10L stainless steel mini kegs are a decent investment and designed for the job.
