Yes, practically, I mean 1740-1790
Captured French Charlevilles were carried by at least one British regular unit for a time, and at least one provincial unit with a very high name recognition.
1758 was a critical year for the British in North America, and there was a major shortage of arms for Abercromby's troops in New England. That year, no less than three concurrent campaigns were launched, one by Forbes against Fort Duquesne/Pitt, Abercromby against Ticonderoga, and Wolf et al against Louisbourg.
The 60th Foote, aka the Royal Americans was technically on the formal roster of British units as "regulars", however, it was raised by recruiting men from Germany and Switzerland, on the condition that it would only be fielded in North America. When the necessary manpower couldn't be recruited, recruits from French POWs, German speakers from Pennsylvania, and a smattering of Irish, and British colonists. When the unit sent a battalion to participate in the Ticonderoga campaign records indicate more than a few in the unit swapped out their Bessies in favor of carrying captured Charlevilles on campaign.
Roger's Rangers, who were NOT on the regular British list of formal regiments, carried their own weapons and were free to use and modify captured weapons, and Charlevilles were at times used because they were lighter, had higher muzzle velocities and a slightly greater range than Besses.
Something worth mentioning is when Louisbourg was captured in 1745 during "George's War", or the one before the French and Indian War, roughly FIFTEEN THOUSAND Charlevilles were part of the arsenal, and fell into British hands. These weapons would have been valuable for the colonial governments to issue or sell to their citizens, and it is likely that some of them were acquired for that use.
