Shame about your Ripple top tube concerns coming home to roost.
Thinking outside the box, would reducing the reach with the following make it fit now? I reckon it would reduce the reach by ~75mm, only thing I don’t know it how twitchy the steering might be with a 35mm stem and a 540mm bar (I’m about to fit that stem with a 747mm “chewy” Knuckleball on my Wazoo).

Buying the above plus the Ripple would cost ~£274 after cashback (if you add another £10 of goods at PX, you can save ~£4 p&p).
A default Poccolino will cost ~£274 after cashback.
Topcashback (I’ve not signed up for Quidco to date, so no idea about them) don’t hammer you with spam e-mails after registering, if you go through the e-mail options, I get typically 1/2 per week. I was very wary initially, but signed up a year ago to get ~£115 from BT for signing up for broadband and phone, I’ve got another ~£10 from other small purchases from PX and Chain Reaction since (I messed up my Halfords one for the Wazoo). There’s a whole range of companies that effectively give you a discount for using a cashback site, for ~£5 annual fee (to get better cashback rates).
