Repulse alongside Renown at the Lofoten action

How would the Lofoten action develop if Repulse accompanied Renown?

Shared fire control and Repulse's experienced crew would probably turn the chase into a damaging British victory, though Repulse would remain vulnerable.

Renown could pass firing information to Repulse, increasing the effective weight and hit probability of their combined fifteen-inch fire even though Repulse lacked Renown's modernization. The German ships could still hurt Repulse with eleven-inch guns, but accumulated damage might force Scharnhorst to abandon Gneisenau or stay in a losing two-on-two fight. The likely result is British damage followed by a British victory, with any escaping German ship vulnerable to later interception.
