No.
The preferred action would be to identify the reason for the duplicate and handle it appropriately by either deleting the alias or renaming the RuleLoader rule in the repository. The goal being to ensure that rule names are unambiguous, certainly across LifeViewer and Golly and ideally other tools too.
If the rules are functionally equivalent then it may be that the RuleLoader version exists because there was no native support for a particular rule family (for example MAP rules) which has since been added.
If the rules are functionally different then it would be worth understanding how broadly the use has been of both and either removing the alias or renaming the RuleLoader rule.
Here is the current list of RuleLoader repository rules that clash with aliases:
This is by design. In both LifeViewer and Golly the various algos are asked in a specific order if they support a given rule string, and as soon as one says it supports the rule it is used. The RuleLoader algo is last in this list so is only used if the rule is not supported by any other built-in algo.
In LifeViewer only you can paste an @RULE definition after the RLE. Again this is only used if no other built-in algo supports the rule name. However in this case it's easy to change the rule name to not clash with a built-in rule or alias.
