Similar story here. Took 50K loss by selling FIFO a few weeks ago. Remainder of shares are at a very low average ($1.30). 30 day window is almost here. Considering buying back in somewhat at that point. However, may wait to see if a R/S happens at some point.
Short answer is no u cant buy calls for 30 days. That said there are get around strategies whereby you sell common, buy the calls, buy the common again, if sequence is appropriate. Dont talk to broker as only source. Talk to tax professional.
