The wider tire suggestion is a very good one. Also, with 28 tires you should be able to have considerably less pressure than 85psi. would think 50psi should be enough. You only need enough not to pinch sidewalls. The idea you need high pressure to reduce rolling resistance/ go faster has been debunked. At 50psi wide tires are like having shock absorbers.

I am not uncomfortable on this bike at all. I am just considering options. Maybe some summer, I'll try aluminum Maes bars just to pamper myself. I use 28mm tires on my touring bike (Manufrance), but the roads i ride on here in central Maine are very smooth, so I can keep high-pressure. I'll usually run the spec on the side of the tire, or up to ten pounds below that. Do you actually run 27" tires at 50psi? I'm only 170 pounds, but that seems low even for me.

Depends a lot on how wide of a tire and also on how stiff that the tire is.

When I installed the (actual) 35mm CST tires I bought from China, I let the pressure drop below 40psi before I noticed any pronounced softness.
Although the tires felt slow even initially, at 52psi, I had slowly become used to their getting slower, so was surprised to see less than 40psi in the rear tire without ever having felt it bottom on any of the sharp road irregularities of my usual travels.
That said, I weigh only 140lbs but my Six-Ten weighs over 30lbs with rack and "trunk" luggage, and with it's suspension seatpost, plus these heavy 1-3/8" hybrid-style tires:

50psi is what I run my 26x1 3/8 tires at, but I don't think I'd ever go that low on 27x1". Not when I'm doing 60-mile rides on them.

27x1" tires can be as narrow as 21mm or as wide as 26mm, the tires I reported on above say 27x1-3/8" and also "37-630", so are much wider at an actual 35mm inflated. About the width of your 26x1 3/8" tires!

I run my 27x1" Paselas at 70-72psi. 27" Paselas run large, so their 27x1" measures a full 26mm wide on touring rims as shown below.
