I wouldn't take that approach. He'll probably give you similar answers to here. Dispensations are for serious problems like health, not just because it conflicts with plans.
You don't need a dispensation for health. If you're too ill, old or frail to attend the dispensation is automatic.
Dispensations by a priest are for pastoral reasons. Avoiding a family conflict is a pastoral reason, particularly when it involves someone elderly.
The Church is not a gulag. Family is very important to the Church. Remember the Sabbath was made for man, not the other way around.
I'll bet the priest will give the dispensation but will say "remind your wife that going to Mass is a serious matter and to please respect the fact that you take your obligations seriously". The fact that the OP would ask the priest is indication enough that he takes the obligation seriously enough to ask for it. Most simply would just miss the Mass.
Code of Canon Law:
Can. 1245 Without prejudice to the right of diocesan bishops mentioned in ⇒ can. 87, for a just cause and according to the prescripts of the diocesan bishop, a pastor can grant in individual cases a dispensation from the obligation of observing a feast day or a day of penance or can grant a commutation of the obligation into other pious works. A superior of a religious institute or society of apostolic life, if they are clerical and of pontifical right, can also do this in regard to his own subjects and others living in the house day and night.
2181 The Sunday Eucharist is the foundation and confirmation of all Christian practice. For this reason the faithful are obliged to participate in the Eucharist on days of obligation, unless excused for a serious reason (for example, illness, the care of infants) or dispensed by their own pastor.Those who deliberately fail in this obligation commit a grave sin.
