Depends entirely on the application of powers. If JJBA has taught us anything; it's that pure power does not inherently mean a win. Namedly; What if D4C -LoveTrain- just pulls Giorno out of the main reality? Giorno would cease to exist in the base reality as only D4C has the ability to allow things  in multiple realities to exist in one space at one time. GER wouldn't be able to just will itself back into the main reality because of the reality lock on it's powers.

(This is Omni-Reality warp vs Fixed-Reality warp.) D4C/Valentine can just hop to a reality where Giorno never existed or simply didnt acquire requiem and pull that version of him back to the 'base' reality (and only D4C has the ability to do or undo this). It is also stated that the only power able to breakthrough -LoveTrain- is the Super Spin. If D4C is already in -LoveTrain- it CANNOT be beaten or touched by anything other than Super Spin. Giorno does not know the Super Spin, let alone how to apply Spin at all. Valentine can affect multiple realities whereas GER only affects the base WHILE IT IS ALLOWED TO EXIST THERE.

^above situations result in a D4C faceroll with no effort at all. Since OP said Lovetrain is active at start and canonically it is stated only Super Spin can bypass the lightwall to affect Valentine or D4C in LoveTrain. Its an absolute roflstomp.
