Description
Current AnimComponent - has a great features and is flexible enough. But it lacks few of the needed features, one of them is animation retargeting.
If transforms of skeleton nodes are different between model and animation file, then it will not play animations correctly, hence retargeting is required. Animation Retargeting pre-processes animation clip data transforms by compensating for the difference in nodes transform differences.
Different engines support various features set for animation re-targeting and is a common practice working with humanoid animations.

Research direction
Start by reviewing AnimComponent and the existing animation clip processing to understand where skeleton-node transforms are handled. Use the issue's retargeting goal to determine the required behavior for differing model and animation skeleton transforms. Done should mean animations play correctly after transform differences are compensated.
