This is far beyond the scope of these forums, whether or not the people here would like to admit it or not. Having said that, being that I have a background in healthcare I felt compelled to do a quick search. It has turned up information that people have investigated running the two together to help mediate corticosteroid induced osteoporosis in humans on several occasions, and probably a few other applications that I didn't get to in the interest of time.

Anabolic steroids in corticosteroid-induced osteoporosis.

Severe osteoporosis represents a major complication of corticosteroid (CST) excess. Steroid-induced osteoporosis is characterized by both increased bone resorption and inhibition of bone formation. Excessive bone resorption is attributed to hyperparathyroidism which is secondary to calcium malabsorption. Calcium and vitamin D supplementation or treatment with inhibitors of bone resorption are of benefit but they usually lead to further inhibition of bone formation. The inhibition of bone formation in CST treated patients is due in part to suppression of adrenal androgen secretion. Thus the suppressed circulating levels of osteocalcin, a biochemical marker of osteoblast activity, in patients on CST can be reverted to normal by administration of anabolic steroids. In a prospective controlled trial in patients on long-term CST therapy we have observed that nandrolone decanoate therapy, 50 mg intramuscularly every 3 weeks for 18 months, induces a transient increase in bone mass within the first 6 months of treatment and prevent further losses thereafter. The sequential biochemical changes indicate that nandrolone decanoate in patients on CST inhibits bone resorption without affecting or even increasing bone formation. Furthermore in patients on CST treatment the virilizing activity of nandrolone decanoate was virtually negligible at least within the 18 months of treatment. These results indicate that anabolic steroid administration may represent a rational and convenient strategy for preventing and treating CST-induced osteoporosis.
HOWEVER, I have read something in the past that would suggest there might be some sort of synergism between AAS and corticosteroids--the AAS might increase the potency of the corticosteroids in a way that can put you in the hospital.

It's probably not wise. But, if you'll be on long-term steroid therapy and you're worried about side effects like osteoporosis, you can probably run the idea past your doc and see if you can see an endocrinologist or rheumatologist who is an expert on such things and can probably answer your questions.
