No.
Tayammum instead of Ghusl is allowed only if Ghusl is not possible e.g. no water, no enough time, health reason preventing Ghusl, etc.
Convenience alone is not a valid reason to leave Ghusl and do Tayammum in stead of it. Ghusl remains obligatory because it is possible even with little difficulty, and in such case Tayammum will be invalid.
Wassalam.
