I think you should stay with XPG and XPE because the XML will be too concentrated in term of heat generation.
When you choose ELN series of mean well I assume you want the dimming ability, so if you design is 3 LEDs in a string, I have a PWM dimmable driver at 700ma, pm me for details
If you are talking about setting the ELN to run about another strings of LED for moonlight than you will need to do resistive circuit which will increase you heat generation a lot-not advisable.
Get a regulated 12V ac/dc and drive both the moonlight 12V LED module and the dimmable driver I mentioned will allow you to have moonlight and dimmer on one power supply. To achieve automatic moonlight and main light on/off separately, just get one more 12V ac/dc and a timer and power the two sets of LED separately.
Please do update, I want to see your angled designed and as I have tempted so many times to put it in the Edge Saviors myself.
