The September 2012 LoAR cover letter says that late-period English surnames can be used as given names: https://heraldry.sca.org/loar/2012/09/12-09cl.html#5
and precedents like the December 2014 LoAR sn. Riane Goch note:
"Blue Tyger documented Ryane as an English byname dated to the 16th century in the FamilySearch Historical Records. As i/y switches are common in English, both Ryane and Riane are plausible forms of this name."
Black's "The surnames of Scotland, their origin meaning and history" p. 728 sn. Sinclair has examples where it's lost the middle t or d including:
SENA NPN1C2a. Attested place names says:
"For example, in Renaissance Scots, the letters i and y are regularly interchangeable. So, a name attested as Armyltoun could also be registered as Armiltoun."
As SENA Appendix C puts Scots and English in the English/Welsh language group, they are compatible with each other, and can have up to 500 years between the name elements.
