我认为最好不要,虽然使用“方便”也不会造成句子歧义,但“便利”在这个句子中充当的是名词,而“方便”一般没有这个用法,如果在这个句子中用“方便”会感觉有点奇怪。
“便利”和“方便”是一组近义词,但它们之间还是存在细微的差别。
I think you'd better not to use "方便". the use of "方便" will not cause the sentence ambiguity, but "便利" in this sentence is a noun, and "方便" generally does not have this usage. It would be strange to use "方便" in this sentence.
"便利" and "方便" are a group of synonyms, but there are still subtle differences between them.
