I highly recommend NOT to consolidate the inputs. Use whatever tool you wish, but I would also recommend what o_e_l_e_o said. Just send every UTXO in various time intervals and you will be more than ok. Keep it simple. That's my opinion, but I must say I am biased because I don't trust Wasabi at all.
It all depends on your habits on how to spend UTXO.
If you tend to spend the large amounts that require a large number of small UTXOs consolidating them during an empty mempool can lead to cost savings.
On the contrary, if you only require a single UTXO for a payment, there might be a different outcome.
