I don't know this plugin, and I don't know witch solution is the easiest, but anyway, since I was writing my function while you were writing your message, here it is (it still is simple):

Put your json file in the config-folder of calibre.
If you make a "replace all", it will load the file only once, during the first passage.

def replace(match, number, file_name, metadata, dictionaries, data, functions, *args, **kwargs):
    """ 
    Replace John|Paul|George|Ringo by Mick, Kieth, Ronnie or Charlie, 
    using a dict {"John": "Mick", ...}
    This dict is loaded from a json file, plaaced in the config folder of calibre.
    """
    from calibre.utils.config import JSONConfig
    m = match[0]

    # first passage
    # Load the dict from a json file and store it in the persistent dict "data"
    # (see the help of calibre for more details about the dict "data")
    if number == 1:
        fname = 'beastones.json'
        data['equiv'] = JSONConfig(fname)
        if not data['equiv']:
            print(f'Problem loading {fname}, no treatment will be done')
            
    # normal treatment
    return data['equiv'].get(m, m) 	# if the json file was not found, no changes are made
