the רדב"ז in מגן דוד אות ש writes that
גם דע כי יש בש' סגולה שאין כמוה בכל האותיות כי היא תשמש ג"כ בשימוש הס' וכמוצאה ממש
"also you should know that ש has a unique virtue in that it can be used in place of a ס"
based on this some say to say a פסוק that starts with a ק and ends with a ש like
Leviticus 21:6 - ...
I found a place in Mishlei (Proverbs) where if you say two short consecutive pesukim the first begins with ק and the last ends with ס, if that's acceptable to say two pesukium for one's name.
Proverbs 16:10-11 קֶ֤סֶם ׀ עַֽל־שִׂפְתֵי־מֶ֑לֶךְ בְּ֝מִשְׁפָּ֗ט לֹ֣א יִמְעַל־פִּֽיו׃
יאפֶּ֤לֶס ׀ וּמֹאזְנֵ֣י מִ֭שְׁפָּט לַיהֹוָ֑ה מַ֝עֲשֵׂ֗הוּ כׇּל־אַבְנֵי־כִֽיס׃
As a general rule, all the letters of אהו"י are interchangeable (Ibn Ezra). One example I found with a quick search is Zecharya 11:13 where a yud replaces an aleph.
UPDATE: I went and found a few more examples:
Here are two cases where the same word is spelled with an aleph in Divrei Hayamim and a heh in Melachim, according to the Radak: 1 and 2.
