RE: Or he refused to finalize a marriage, by the act of bedding his own wife.

How do you know that Uriah never bedded his wife or never, EVER consumated his marriage? What verse tells us that?
All we know is he did not feel it was right for him to enjoy the special privilege of the comfort of his home and wife while he knew that his comrades were fighting and risking their lives in battle.
Also, when David bedded Bathsheba, did he know anything about Uriah and Bathsehba’s bedroom habits? Did he know when they had sex and how often? You will be hard press to tell me yes. All we know is that he saw her bathing and was attracted to her ( a married woman ). David then had sex with her and impregnated her.
Uriah was brought back after David found out that he had her impregnated and wanted to keep his fatherhood a secret. THAT was the reason he called Uriah back to his house ( hoping that Uriah would bed her and cover his adultery with Bathsheba, making the world think that the child was Uriah’s).
I think your explanation is quite fanciful.
It’s up to you now. Use what you know about today’s media. About what sells into the common marketplace.
