Welcome to FlyerTalk first of all.
No risk when it comes to remote stand/bus to terminal (QR pays for a gate) but the 5:45-7:35 option seems a bit 'stretched' (not to say risky) to me: you would probably be okay assuming all on-time (say you would be collecting your bags just after 6:15, drop your bags again and clear security before 6:45) but even a slight delay could compromise the whole thing and I'm not sure I'd risk it.
