Wow! I'm goin to have to be reminded why you would ask me a pointed question. I do know that I have no clues about t/ feast of tabernacles, accept from what I've picked up here.
Whatever you choose to Glorify your God w/ will bring Glory to His Name! (as long as it ain't somethin blasphemous!) That's where I'm at.
He wants us to draw as close to Him as we could humanly possibly get w/o falling down dead.(LOL) He doesn't look to see if you've built a tabernacle for Him according to t/ specifications of building tabernacles. My tabernacle is w/in me! Everlasting, Always Abiding as long as I keep myself "pure" for His Presence. And even Christmas Day, December 25th can be a Special Day Honoring Christ, t/ Everliving King. T/ actual date can be in err but t/ Heart of t/ person celebrating t/ Gift of God is as Perfect to God as t/ actual Day, Christ Jesus was Born! Be careful though not to waste precious vows on something like that unless you have t/ discipline to carry them out. You know what He thinks about vows.
So, beware that we not prejudice t/ events that others have honored God in or with. Sure, t/ heathen will always be among us & not appreciate t/ Glory of t/ King - Jesus; but we can!
sincerely & for certain,
Jack Swanger, t/ Swangman!
