The sonnet is an older form of verse, in which the lines must total to fourteen, which makes the style lean toward the terse, in order to express all that you mean. The foot must be iambic - that's "dee DUM"; you may try substitutions but take care since readers (if you write it, they will come) may feel your rule-departures are unfair. Perhaps, indeed, it really would be best to toss the thing away - into a pile of verse forms that deserve a permanent rest - away into the wasteland, vast and vile. Sonnet, begone, and from this April hence, for all of time please make yourself past tense.
Such is the rule
of the April fool.
