I think this is overall a good interchange design. I like the creative way to separate traffic headed for South Tacoma Way from the I-5/SR 512 interchange. I also appreciate you squeezing in some direct connectors for future HOV lanes, though since your drawing is not to scale, I'm not sure whether they'd actually fit as you've drawn them. I'm also a little worried that the ramp to the P&R being so close would cause a weaving issue.
I do have one concern in that traffic currently backs up on the WB 512 to SB I-5 Ramp due to the tight curve on that loop ramp, which largely remains unchanged in this design. The HOV direct connector would help mitigate this by effectively adding another lane, but still being a loop ramp means the movement will have limited capacity regardless, due to the restricted speed around the tight curve. I see one reason you have for this design is to keep the clearance low for the McChord Field approach, however the interchange is about 4000 feet beyond the start of the approach surface for the runway, which gives a clearance of about 80 feet above the end of the runway at the surface's slope of 50 to 1, which should be more than enough to build a flyover bridge. There are certainly other issues that might make a flyover hard to fit in within the constraints of the interchange, especially without needing to take additional property, so the loop ramp option that you've drawn up still may be the best option.

WSDOT released an update to their WSF service restoration plan today, in which they say they don't expect to start serving Sidney, BC again until "at least spring 2030". Yikes.
Their February 14th update listed the timelines for the remaining routes as "early 2023" for Fauntleroy/Vashon/Southworth, "spring 2023" for Seattle-Bremerton and Port Townsend-Coupeville, and "not... any sooner than Summer 2023" for Sidney, BC. All of those routes have been pushed back -- fall 2023 for F/V/S (with additional weekday service starting in the spring), October 2023 for Bremerton, and spring 2024 for Port Townsend.
And even those dates seem a little optimistic, since they're still having to cancel trips due to crew issues from time to time, primarily on the Point Defiance-Tahlequah and San Juan Islands routes, in addition to their well-documented shortage of reliable ferries.

We do have a ferries thread: https://www.aaroads.com/forum/index.php?topic=30325.0

Random question... why are commercial vehicles (trucks/buses) banned from using the Peach Arch border crossing between BC and Washington? The only information I can find online is that it's been that way since 1970, but no explanation as to why that's the case. Any insight appreciated!

There's a separate truck customs parallel to the Peace Arch crossing about 1/2 mile east.
