Need some aesthetic suggestions, 90s Merlin ti frame for wife

Does mid-90s count as vintage? Maybe just "mature." In any event, I'm redoing my wife's 1 Merlin (full DA down to the hubs) for her birthday -- Merlin have sent me a new sticker pack, I'm in the process of stripping off the old, deteriorating stickers, and am changing her decades old color scheme (red sidewall tires, red/black double diamond weave bar tape and red Selle Italia Gel Flow from around 2000?).
I'd like to avoid boring old black (seat/bar tape), she's not really a fan of primary colors. But I thought gumwalls with tan leather look bar tape and a Brooks B17 in honey. But maybe that's too "faux vintage." Other ideas are a more modern look, with one of Brick Lane Bikes' multicolored weave bar tapes and upsized to 25mm blackwall tires (I like the black tire/black rim look) and a new Gel Flow (which still has something of a period profile.) Not sure I can fit 28 tires but would love to.
Any other ideas? She's a recreational rider at this point, she'll go out with me on 30-50 km country rides but not much else. Thanks!
It's basically this bike, but with black rims and shorter SR stem:

Gum wall tyres look good on most bikes, but get the real gum wall, like Vittoria or Challenge, not that horrible painted censored like Continental
