Personally, I feel the OP's batteries can be married. But, I can never recommend this becuase there are too many variables I don't know about.
While I've never gone out of my way to use wildly different batteries, I've never married or rotated batteries. In order for there to be a problem one of them either has to rise to about 160°C (to vent), over 250°C (to go into thermal runaway), or drop below zero volts. These are tough conditions to reach.
Even if you used a new 1500mAh battery with an old 3000mAh battery (with high internal resistance), in parallel you have no problems as they will always discharge down at the same voltage once they're allowed to rest and equalize. It can matter in series if you're charging via USB but the mod usually signals low battery before one cell reaches zero volts. And any voltage differences between them is reset every time you charge.
Having said all this though, I will always recommend marrying from the start. Just too many variables so I have to go with the safe recommendation.
