For one, you're on HRT, yes, but make sure blood levels are appropriate. Non-optimal HRT can't be expected to have optimal results.
Apart from that... I wouldn't be as extreme as muuu says to be, but yes, losing weight would probably help a lot if you're overweight or in the higher ranges of your alleged healthy weight. The more fat you have, the harder it is to move it around, and the least burn/regain you have, (probably) the slower fat redistribution will be. As long as you make sure you do it healthily, there's no harm in losing some weight, assuming you're not becoming underweight in the process.
Also, I think if you lose weight, your muscle mass should reduce a little bit more. The heavier the body is, the larger the muscles get to support it, no?
Apart from that... of course, physically moving fat around can help a lot, sure, but it's probably not needed to achieve satisfactory results.
